This is one of my very favorite books so this is going to be a very long review. I do, however, give some recommendations for supplementary reading for those who are struggling with this work at the end of my review so if you are looking for secondaries on Deleuze's reading of Nietzsche you can skip my lengthy review and go right to the end. There is not a lot of material on Deleuze's reading of Nietzsche in English but I have listed what I think are the best resources I have come across so far.

Nietzsche and Philosophy is meant to be a systematic examination of the work of Friedrich Nietzsche but, as with nearly all of Deleuze's commentaries on other philosophers, it winds up being just as much about Deleuze's own ontology as it is about Nietzsche. In fact, this book is probably the best place to begin a study of Deleuze's often obscure ontology.

The fact that this book is as much about Deleuze as it is about Nietzsche does not mean that it is without value considered purely as a commentary on Nietzsche. In fact, I think Deleuze gets a great deal of Nietzsche right in his interpretations. If one ignores some of Deleuze's more controversial interpretations, like his interpretation of the eternal return, this book is one of the best and most profound systematic reconstructions of Nietzsche's philosophy around. No one will be able to claim after reading this book that Nietzsche was not a serious philosopher. The old image of Nietzsche simply throwing out random aphorisms without any systematic intent will not survive even a cursory reading of this book.

In terms of understanding Deleuze's ontology there are a number of key notions in this work that can be "mapped" onto Deleuze's own ontology: sense, genealogy, active and reactive forces, affirmative and negative will to power, critique, and anti-dialectics. I will attempt to summarize these aspects of Deleuze's book in as concise a way as possible.

I will begin with active and reactive forces and affirmative and negative will to power since these are the bedrock on which the other notions are built. It is important first to realize that for Deleuze there are no "things" in the ordinary sense. Deleuze's ontology is an ontology of becoming so it is more accurate to talk about things in terms of forces than of things. However, it would be a mistake to attempt to view forces as metaphysically distinct from things, or, as constituting a metaphysical realm beyond the world of appearances. Deleuze follows Nietzsche in his attempt to dismantle any kind of "other world" beyond the world of appearances whether this be a realm of pure Ideas in the Platonic sense or a world of force. It is the fiction of positing force as separate from their expressions that lies behind the triumph of reactive forces, but I am getting ahead of myself.

To understand what Deleuze means by force it is better to think in terms of his distinction between the virtual and the actual. The virtual is a tendency, or what a force is capable of, and the actual are the actual manifestations of that tendency. So we can think of love, for example, as a tendency and marriage between a man and a woman as one possible actualization of this tendency. Deleuze believes that to understand what something really is we need to move from the actual back to the virtual and this is because the triumph of reactive forces tend to separate forces from what they can do so that we wind up defining forces in terms of their actualizations rather than in terms of their tendency. I chose the example of love on purpose because reactive forces have, in our culture, often defined loved purely in terms of a single form of its actualization, i.e. marriage between a man and a woman.

Reactive force separates force from what it can do by placing limits on active forces (the force of love). Deleuze wants us to move back from these actualizations to the active forces (the virtual) behind them, i.e. to make reactive forces active. We should not define any force (love, thought, science, philosophy, etc.) purely in terms of what it is but in terms of what it can do and we often do not know precisely what a force can do. This allows us some room for experimentation. Deleuze's ontology is a radically creative ontology. We should not be defined by our current limits. Thought should not simply be a matter of reflecting what is (the dogmatic image of thought) but should be a way of creating new possibilities of life.

It is important to get Deleuze's interpretation of active and reactive forces right because the way Deleuze (and Nietzsche) often talk about them can lead to confusion. Deleuze, for example, refers to Nietzsche's example of the lamb and the eagle. The lamb does not want to be eaten by the eagle so it creates a fiction by separating the eagle from what it can do and making it morally responsible for its actions. This example makes it sound like Deleuze and Nietzsche are advocating for a view where the "strong" can simply go around preying on the "weak" either by killing them or enslaving them. But as Deleuze (and Nietzsche) point out the desire for power over others is always reactive. When Deleuze talks about the "strong" he does not mean those who enslave or dominate others, he means those who are active (and he uses the term active in a very precise sense). It is not a matter of quantity; in other words, a weak force is not weak because it is weaker than another force but because it places limits on what it can do. So the world Deleuze (and Nietzsche) are describing is not a world in which "strong" human beings are enslaving or dominating the "weak". The world Deleuze (and Nietzsche) are describing is a world in which everyone's creativity is expressed to its maximum, where there are no undue restrictions placed on active forces (like love).

The will to power is not identical to forces but is a principle of the synthesis of forces. This can be understood in this way: every "thing" in the world is a synthesis of forces. There cannot be a singular force because in order to know a force there must be another force acting against it. In this relation there will always be one dominant and another dominated force. But there are different ways of synthesizing these forces. When active forces are allowed to triumph over reactive forces we have an affirmative will to power (a will to power which affirms becoming and the virtual without placing undue restrictions on active forces). A negative will to power is one in which reactive forces triumph, not by creating a force superior to active force (that would make them active), but by creating a fiction in which active force is separated from what it can do and becomes morally responsible. This leads to ressentiment, bad conscience, the ascetic ideal, and the other-worldliness of religion. This is the negative will to power which negates this life and creates the fiction of another life. There is a whole psychology built around this negative will to power and it is the psychology that has dominated Western history. In fact, Deleuze believes that Nietzsche presents a psychology of the unconscious which is rival to that developed by Sigmund Freud. I do not have the space to explain the details of Nietzsche's psychology of the unconscious but Deleuze's interpretation of it is quite interesting. Stated briefly we can say that the affirmative will to power is the becoming-active of forces, and the negative will to power is the becoming-reactive of forces which leads to nihilism.

This ontology (and psychology) of active and reactive forces lies behind Deleuze's notion of sense. Another one of Deleuze's radical ontological claims is that nothing has an essence. We can only understand a thing if we understand the forces that have appropriated it. It is impossible, for example, to provide a single definition of something like religion. What religion is depends on what forces appropriate it. Religion can be appropriated by reactive life denying forces in which case it becomes reactive and nihilistic, or, it can be appropriated by more active life affirming forces in which case it can be something relatively life affirming (I say relatively because Deleuze believes that things have more of an affinity with one kind of force, and he believes that religion has more of an affinity with reactive forces; I am not sure I agree with him but I do not have space to examine this question in detail). This might sound like a strange notion but it actually makes perfect sense. We cannot apply a single definition to religion that would apply equally to the religious zealot and the saint, or to the bigot and the zen master. Religion can be many things, including as Marx said, the opium of the people, depending on what forces appropriate it. But it would be wrong to say that religion simply is "the opium of the people" or attempt to offer one definition that would apply to all cases. This is what Deleuze means when he says that we cannot understand something unless we understand the forces that appropriate it.

This leads us to the method of genealogy. The genealogist is engaged precisely in attempting to ask this question, i.e. what forces have appropriated this thing? Deleuze presents this as a difference between asking the question, "what is it?", which has been the standard philosophical question since Socrates, and asking "which one?". The answer to the latter question is not a personal question, i.e. the answer is not going to be "George" or "Susanne". The answer will be either an affirmative or negative will to power. This is what the genealogical question attempts to answer: is this thing (thought, phenomenon, system of philosophy, etc.) the result of an affirmative or negative will to power? Is it a result of a noble or a base form of life? Is it the result of love or hate?

This question is tied to Deleuze's transcendental empiricism. Deleuze is not looking for general conditions of possibility but the real conditions of genesis of things. These real conditions are not wider than the phenomenon which they condition. So, to give one example, if we ask "what are the conditions of philosophy?" we first have to say, "philosophy can mean different things based on what forces appropriate it". If we then narrow the question and ask, "what were the conditions of Platonic philosophy?" then our question becomes more specific. Deleuze will not answer this question by providing a general condition like "the human faculty for thought", or "an innate desire for metaphysical knowledge". Deleuze is not looking for general conditions which can apply to any particular philosophy but the real conditions of something like Platonic philosophy, and he might answer that the real conditions for Platonic philosophy were present in Athenian democracy which required a method for determining the validity of opinions, or, of separating valid from invalid opinions. Plato's theory of Forms responded to this precise problem (this is an example Deleuze gives in 
What Is Philosophy? ). Whether this particular answer is right or not is not important. What is important is that Deleuze is not looking for a general condition for human being's philosophical activity in general. Deleuze believes that thought is always a response to actual problems so Plato's theory of Forms is not a result of a general human faculty for thought but is a specific response to a specific problem. We can then ask whether this philosophy expresses an affirmative or negative will to power which is the genealogical question.

One of Deleuze's ultimate goals is to critique a dogmatic image of thought which he thinks has been dominant in the history of Western philosophy. The problem is that thought has been determined as having a natural affinity with values like truth. Deleuze believes that Nietzsche is attempting a radical critique of values like truth by asking questions such as: who is it that desires truth? what is the will to power behind the search for truth? Deleuze (and Nietzsche) will answer that it is the reactive human being who desires truth. This reactive image of thought winds up separating thought from what it can do. Thought is capable of simply reflecting reality but this is not all that thought can do. Thought is creative. It can create new possibilities, new ways of living and thinking, and if we limit thought to simply reflecting reality truthfully we wind up separating thought from what it can do, and ultimately we wind up leading a reactive life. Deleuze (and Nietzsche) will, therefore, submit these heretofore highest values (like truth) to a critique through the genealogical method I outlined above. Deleuze believes that we should not simply be asking whether a thought is true or false. There are plenty of "base" truths. We should also ask whether a thought is noble or base, or a result of love or hate. These latter values are just as important (if not more so) when examining thought as the value of truth. This critique leads to a transvaluation of all values, which means, a new principle for determining the value of all values. It is necessary to submit values themselves to an evaluation to determine their value, and this value will be determined based on whether they express an affirmative or a negative will to power.

I want to briefly say a word about Deleuze's anti-dialectical stance in this book before bringing this overly long review to a close. Deleuze is opposed to dialectics because he believes it exchanges a purely external difference for an internal difference. For example, my table cloth is blue and my shirt is red. Red, as a particular determination, includes negation (i.e. red includes the determination not-blue). This is an example of the famous slogan "determinatio est negatio". The problem is this kind of determination does not get to the most profound differences. Differences between colors, for example, are simply differences of degree for Deleuze (they express the same universal or the same tendency). If we take examples like this and attempt to work out a theory of difference from that standpoint we will wind up with a superficial understanding of difference (Deleuze attempts to work out a more adequate concept of difference in 
Difference and Repetition ). We wind up confusing differences in kind and differences in degree. This, in a nutshell, is Deleuze's critique of dialectics (and Hegel). Hegel begins with these differences and attempts to determine being from the standpoint of these kinds of differences without realizing that these differences are merely the expressions of more profound differences which cannot be grasped by the dialectic.

I would also like to briefly recommend some works that I think are helpful in elucidating Deleuze's book on Nietzsche (which is not always an easy book to understand). Unfortunately there is not an overwhelming amount of scholarship on Deleuze in English yet (I think his time is still coming). But there are two books that I think provide helpful commentaries on Deleuze's reading of Nietzsche. The first is 
Gilles Deleuze: An Apprenticeship in Philosophy  by Michael Hardt, and the other is  Deleuze and Guattari (Critics of the Twentieth Century)  by Ronald Bogue. Both of those books have chapters on the Nietzsche book which are quite good. And there is one article that I think is absolutely essential reading for anyone struggling with Deleuze's Nietzsche book. It is called, "On the Presence of Bergson in Deleuze's Nietzsche" and it is by Giovanna Borradori. It originally appeared in Philosophy Today, 1999, vol. 43. Most commentators do not explicitly attempt to tie Deleuze's reading of Bergson in with Deleuze's reading of Nietzsche because Deleuze's book on Nietzsche was written before his book on Bergson. But as Giovanna Borradori rightly points out Deleuze had already written an important article on Bergson called, "Bergson's Conception of Difference" which predates the Nietzsche book. It is very difficult, in my opinion, to understand Deleuze's reading of active and reactive forces in the Nietzsche book without understanding his reading of Bergson and Giovanna Borradori does an excellent job providing the necessary background. I will also add that the essay on Bergson by Deleuze was apparently unavailable in English when Borradori wrote her article but it is now available in  Desert Islands: and Other Texts, 1953--1974 (Semiotext(e) / Foreign Agents)  for anyone who wants to read it.
